POWER-1.00M FOR WEAVIN G DOUBLE PILE 0R TUFTED CARPETS' AND OTHERFABRICS.

Specification of Letters Patent.

Application filed November 7, 1919. Serial No. 336,375.

To all whom, it may concern:

Be it known that I, BENJAMIN SINCLAIR SMITH, subject of the Kin of GreatBritain and Ireland, residing at?) Marshall, street, Manly, near Sydney,New South Wales, Australia, have invented certain new and usefulImprovements in Power-Looms for eaving Double File or Tufted Carpets andother Fabrics, of which the following is a specification.

The primary object of this invention is to produce double pile Axminstercarpets in a vertical type loom, splitting the double fabric after eachmovement of the lay. Two carpets are thus produced simultaneously. Theloom in which the invention consists is also usable for the productionof plush and other pile fabrics on the same principle.

In looms heretofore known wherein double pile carpets or plush fabricshave been manufacturedand split during manu facture, a great waste oftuft wool was un avoidable as the wool threads were floated behind orbetween the warps and a limited part only of the tuft wool was utilizedfor forming the pattern. Pile goods, manufactured by the loom formingthe subject -matter of the present invention, are manufactured at amaximum economy because each pile tuft is looped around the weftthreads, and buried only at the, loop, where it is bound in the warpchains, so that there is a negligible quantity of the pile wool buriedin the weave, substantially all of it being exposed in the pile andpattern, the ground work ,of the carpet or other pile fabric beingconstructed practically wholly of the warp and weft threads. It isalready known in the art that single ply carpets or pile fabrics may bemade with this economy of pile wool but it was not practicableheretofore to make split double pile goods so as to procure thisadvantage of economy.

The lay carries the reed and is retired to offer working clearance forthe wool selectors, the folders, and the grippers during the crossing ofthe warps, the insertion of the wefts, and the cutting and folding ofthe pile tufts. The warps are disposed vertically below overhead warpbeams, and the wefts are inserted in the sheds by needles. The reed isconstructed as a grating which works in the dents between the warpchains sponding top I woven split pile goods may be manufactured withmaximum economy. These supplemental features notably include oscillatinwool selectors which deliver the tuft wool t reads to picker gripperswhich work through the dents in the warp chains, drawing the wooltherethrough and laying it over the wefts, an oscillating top knife bywhich the tuft lengths are severed when so drawn and while still held bythe grippers, and a d0u-' ble folder for the tufts.

The following description, subject to what will be stated hereinafterdefinitely with ig. 1; Fig. 14: is a sectional plan of the reference toFigs. 32 and 33, is to be read as referring to my loom when operatingwith two warp beams and three heddles.

50 is the fixed heddle frame, 51 and 52 the oscillating heddle frames,53 and '54 the stationary warps, both of which are drawn from stationarywarp beam The tension on this beam is set by a load weight 56 hanging ona brake lever 57 which pulls a brake band 58 bearing on the hub of theroll. The stationary warps 53 and 54: are carried through fixed eyes 59and 60 of fixed heddle 50. The four crossing warps are drawn from thewarp beam 61. They are carried over whip rolls 63 and 64, and over aguide roll 62. There are in all four of these warp threads, two goingover the roll 63 and two over the roll 64. Thence these warps go to theeyes of the oscillating heddles 51 and 52in alternate pairs arranged sothat when the heddles are oscillated the four warps are crossed, two tothe right and two to the left, thereby forming two parallel sheds ineach of which a double weft thread is set to form the fabric of a doublepile carpet.

Rotation of the warp beam 61 is controlled through a worm wheel 65 whichis turned by worm 66 on the end of a vertical shaft 67, on the lower endof which a detent wheel 68 is fixed, as shown in Figs. 5 and 6. A swingarm 69 centered on shaft 67 carries a tripping sector 70 which isadapted to engage a spring pawl 71 carried on rocking arm 72, which iscentered on shaft 67. The arm 72 is oscillated to and fro by work arm 73and a bell crank. The power arm 71 of this crank carries an offset pin75 which is free to run in a long slot 76 on link 77, the lower end ofwhich is pivotally connected at 78,to lay 79. At each reciprocation ofthe lay the linkage and lever mechanism hereinbefore described causesreciprocating motion of pawl 71, so that said pawl engages the detenttoothing on wheel 68 and applies stcp-by-step motion iherethrough to theshaft 67, and so applies regular rotational feed motion to ,warp beam61. The swing arm 69 is under control of lever arm 80 which may beintegral with it, and said lever arm 80 is connected through pin 81 to areciprocable link 82 which is a pair link to link 83 seen in Fig. 2, andmoves with link 83. So long as link 82 is in the right hand position(see Fig. 5) the sector 70 is held clear of the pawl 71, so that thepawl operates normally to apply at each movement a step-by-step movementto shaft 67. \Vhen, however, the link 82 is moved over to the left, itfunctions to swing the arm 69 and thus bring the sector 7 0 under theangular toe of pawl 71 so as thereby to lift said pawl out and hold itclear from engagement with detent wheel 68. T lllS control movement isautomatic and is dependent upon whip rolls 63 or 64 as the case may be,

rest or liberate the action of the results in the dropping of thecorresponding weight 84 or 85 and a consequent transverse movement oflinks 83-82, resulting-in the engagement of sector 70 with the pawl, and

which heddle cams 108-109 turn. Once in each rotation of cams 108-109 acomplete to and fro oscillation is applied to heddle frames 51 and 52'sothat the warp threads are crossed to form the sheds.

When the five heddle arrangement is in use the back gear is disconnectedand all the v cams turn with shaft 113.

As best shown in Figs. 1, 12 and 14, cam 'shaft113 is driven throughreducing spur 75 gears 115-116 from primary drive shaft 117 whichcarries fast pulley 118 and loose pulthe consequent arrest of the feedmotion\ley 119. '120'i a belt shifter which is conapplied to warp beam61. Any slackness in the warps is thus compensated. Completecompensationas between the two pairs of crossing warps is thus obtainedby the compensating linkage described operatin toareeding device on warpbeam 61, uniform tension being always maintained on the war s on beam 55by means of wei ht loaded rake strap 58. In practice, the ouble endedbalance levers 86 and 87 are cross connected in pairs, and there arefour balance weights and not merely two as would appear from thedrawing, Fig. 2.

Heddles 51 and 52 are respectively moved by harness links 88 and 89,which are pivotally connected to the heddles at one end and at the otherends are pivotally connected to the top ends of heddle levers 90 and 91.These heddle levers, as shown in Fig. 2*, are respectively arranged inpairs, one pair being keyed to rocking shaft 92' and the other pair totubular shaft 93 sleeved over rocking shaft 92. When the tail ends 94and 95 of lever arms 90 and 91 move, the heddles 51 and 52 arereciprocatedacross the weaving bay of the loom to effect the crossing ofthe warps. Reciprocating motion is applied to lever arms 94-95 throughlinks 96-97.

- Said links arepivotally connected to lever arms 98 and 99 respectivelykeyed to shaft 100 and sleeved shaft 101. These shafts in turn, asshown-in Fig. 9, are rocked by lever are mounted on a sleeve 114 whichworks on said shaft 113. Sleeve 114 is back geared through the spurwheels shown in Fig. 10 so as to reduce its speed to one-half therotational rate of the'shaft 113, as it is necessary that the left handportion of shaft 113 which carries the assembly of cams having otherfunctions, should turn at twice the rate at back wefts 122-123 shown inthe same figures; Cam 121 which controls the face weft is cut to applytwo motions to the needles associated with it for every .one movementapplied to the similar needles controlled by back weft cam 124. Cams121-124 areboth face groove cams acting respectively on levers 127128.Said levers, and other levers to be hereinafter mentioned which areoperated by similar cams on shaft 113, are all fulcrumed on arbor shaft112. 130 is a counterbalance weight on lever 127, and 131 is a 100similar weight on lever 128..

The outer ends of levers 127-128 are connected respectively by links132-133 to intermediate levers 134-135. In Fig. 12, link 133 and theintermediate lever 135 stand im- 0 mediately behind link 132-and lever134, respectively. The point of connection of links 132-133 tointermediate levers 134-435 is at positions intermediate between theends,- and the fulcrums of those levers are located onshaft 117, so thatthe range of movement at the outer ends of levers 134-135 isproportionately increased, thereby obtaining a longer stroke than thestroke applied to 1e.- vers 127-128 by cams121-124. This augmentedstroke is required for the purpose of obtaining the-necessary range ofmovement of crank levers 137-138 to which it is transmitted throughlinks 181-182, the long arms of which crank levers are connected byshort links 139-140- to needle carriages 143-144. The former of thesecarriages 144 carries back weft needles 145-146. These carriages runrespectively on rails 147-148, the rails and slide blocks 149-150 beingdovetail fits and secured together by back plates which make up thestructure of each carriage. The carriages are incapable of lateralmovement on rails 147-148 but slide freely along them. The faceweftcarriage 143 makes two complete movements for cated immediately everyone complete movement performed by back weft carriage 144, this movementbeing applied by its cam 121 the groove in which is shaped to apply thedouble motion in each rotation to lever 127, while the groove in cam 124is out to apply a single motion only to lever 128 in each rotation. Thisdouble movement is required as there are twice as many face wefts asback wefts in the weave. The face weft carriage 143 is provided with astriker roller 151 on its upper part, and back weft carriage 144 issimilarly provided with a striker roller 152 which is carried on bracket153. Both striker rollers 151-152 are located close to each other but soas not to contact during the crossing movement of the carr1ages. Theirfunction is to engage the levers which control the shuttle movements andthe selvage lay movement, each needle movement calling for a shuttlemovement to form the selvage. From the outer end of the intermediatelever 134, as best shown in Figs. 1 and 12, a link 154 is connected upto a power arm 155 of a bell crank lever having its work arm 156connected by link 1 5 7 to a pull and push rod 158 which is attached tothe slider 159 on which is mounted the pile splitting knife 160. Thisknife is a long blade or as sembly of blades formed with a sharpenedinvected edge 161, and, as shown in Figs. 2 and 19, is locatedimmediately below slot 162 between the cheek angles 163 which arelobelow pile gage cheeks 164-165. The function of this knife is to splitthe woven double carpet as it comes down through the slot 162 and permitthe two single pile car ets thus produced to ass on to the take 0 spikerollers'166-167. Fig. 2 shows the split carpets 168 and 169 assing 'fromspike rollers 166-167 over idlers 17 017 1, and thence to take off beams172-173. The spike rollers are geared together .through spur wheels174175, and drive is applied to roller 167 by mechanism hereinafterdescribed. Take off beams 172-173 are fitted with step-by-stepwindingmechanism which is actuated by other mechanism also subsequentlydescribed. Lever arms 155-156 are respectively fixed on the ends of arock spindle 176 which is carried in a bearing 177, said bearing beingsupported in a bracket 178 on the under side of the loom frame. Rod 158which actuates the slider 159 is guided in a bearing 179 to assure itrectilinear movement, notwithstanding the throw of link 157. The slider159 Works on a dove-tail shaped rail 180, as will be seen in section inFig. 2 7

The pile splitting knife movements are obtained from the face weft cam121. Said knife makes two complete reciprocations at each movement,thereby insuring by double cut the severing of the tufts of the pile andeliminating risk of tearing out tufts which might be missed if the knifewere to make on lly one reciprocation at each movement.

he needles consist of long tubes (146-145 being the back weft needles,and 141-142, positioned between the back weft needles, the face weftneedles). Each of these tubular needles is armed with an eyed head, thedetail construction of which is best seen in Fig. 21, the tubularportions operating only as stems. The needles are guided in cradle races183 which support their overhung weight and insure parallelism of theirmotion. In action, the needles pass across the weaving bay through thewarp sheds and coact with the shuttles at the far side of said bay,carrying the weft threads across the sheds, engaging them with theshuttle threads, and bringing them back. At the near side of the weavethe weft threads are bound by the warps. The weft threads are carriedthrough the tubular stems of the needles from an eye plate 184positioned on the left hand frame of the loom immediately behind thecarriages, as shown in Fig. 1, the threads coming from bobbins locatedin any convenient position laterally of the loom. The thread passesthrough the throat 185 of needle head 186, and through the back groove187 behind needle jaw 188, and thence out through needle eye 189. When aneedle is traversed through the shed, drawing the weft from the lefthand side of the weave across the shed, the forward thread lies in anangular position as shown at 190 Fig. 21, leaving room between it andneedle jaw 188 for the shuttle 191 to pass through loop thread duringthe retiring movement of the needle while the back throw of the weft isbeing payed out by the needle under tension. In the forward movement offace weft needle carriage 143, as shown in Fig. 1, striker 151 thereonengages tappet 193 and through it turns crank arm- 194, pulls link 195,turns bell crank 196, pulls link 197 and turns the spring retired bellcrank 198 and suspension link 199, then operates toggle joint 200, shownin Fig. 20, and releases the four spring claws 201 which hold up theshuttles 191 in their respective upper compartments in shuttle box 202.The position of the needles in relation to the idle position of theshuttles is shown in Fig. 20. Continuing its forward movement, theneedle carriage kicks up spring pawl 203 without performing anymechanical action, and passes on until it strikes bell crank 204 Wll1Cl1is connected through link 205, spring .retired bell crank 206, link 207,and bell crank 208, to suspension link 209, and thus raises said link209 and so moves up finger bar 210, said bar carrying fingers 211 whichact beneath the several shuttles 191 to lift them. The shuttles, as theyappear when in the. raised position, are shown dotted in 192 and to holdthe bight of the weft the upper part of Fig. 20. I After the eyes of theneedles have entered the shuttle race, the rising movement of theshuttles commences, and it continues during the further movement of theneedle head through the shuttle race, the long jaw of the needleofi'ering clearance for the full length of the shuttle to move up andpass the needle to draw through the selvage thread before the needle eyepasses back'beyond the shuttle race. In order to enable the shuttles toenter the compartments in the upper part of needle box 202, springholding claws 201 must be eased to offer clearance. This is effected, asshown on the left of Fig. 1, by means of link connection 212 which ishung up to the 100m frame by a spring 213 at its rear end, so that saidrear end is caused to bear upward against a finger 214 on bell crank'194operating said bell crank through the trip independently of its tappet193, and through the medium of the link and bell crank mechanism alreadydescribed to bend toggle joint 200 and thereby ease back the springclaws. As soon as the carriage .passes tappet 204 and releases it,spring 215 acting on. bell crank 198. operates to straighten out toggle200 and close the spring jaws on the shuttles, thereby holding them inthe shuttle compartment into which they have been raised as already de-'scribed. The threads carried by the shuttles are thus brought up throughthe loops in the weft threads at the needle eyes. When the needles havemoved backward-until strikers 151-152 engage pawl 203, they operate.through said pawl to move lever 216 downward and thence by means oflink 217, bellcrank 218, link 219, bell crank 220, and link 221 (theupper portion of said link 'being shown broken away in Fig. 1 forclearness of explanation) to operate selvage lay 222,

shown in Fig. 19, dropping said lay and thus forcing down the bight ofthe weft into thelbottom of the shed close up to the shuttle threadswhich form the selvage wa'rps. This lay is a narrow presser foot whichis located laterally of but close up to the warp threads and does notinterfere with the crossing of the warp threads in whatever position itmay be. Bell crank tappet 204 is moved only a short distance whenengaged by the striker on the needle carriage, and immediately theneedle carriage commences its retiring movement, bell crank 204 andparts connected thereto resume their normal rest position under tensionof spring 215. The result of this is that the spring claws are operatedmomentarily only but in proper timing to admit entry of the shuttlesintothe upper shuttle box compartments and to I grasp and hold theshuttles after they have entered said compartments. In the furtherretiring movement of the needle carriage, the

without causing any mechanical action.

When the fullback position of the needle carriage is reached, the fallof the weft thread has been drawn clear through the shed so that adouble weft thread is thus laid in the shed. At this point the cross ingof the warps occurs. In the next move ment all four needles move tothrow another pair of face weft threads and a pair of back weft threadsin the sheds. The wefting movements are thus alternated, in one of themface weft threads only being thrown while in the other of them face weftand back weft threads are thrown.

Tappets 193, 203 and 204 are actuated by either of the strikers 151-452.As the up- .dles are brought into action in another timing ashereinafter explained the tappets are actuated by one or other carriage,so as that whenever a needle is advanced to the shuttle box the shuttleand selvage lay actions already described are caused to occur.

223 is a rock shaft through which rocking motion is applied to thefloating frame and vertical movement is applied to the lay. This shaftis utilized to carry the bifurcated hubs of three levers. The third cam224 applies oscillation to rock shaft 223. The fourth cam 225 operatesthe tuft folders and the take off spike rollers. The fifth cam 226operates the pile grippers. The sixth cam 227 operates the jacquardcylinder. The seventh cam 228 operates the comb board of the jacquardmachine. The eighth cam I229 operates the top knife by which the piletuft lengths are cut off. The ninth and tenth cams control the heddles.

The third cam is structurally identical with the fourth cam, which isshown in Fig. 8. It acts through an offset tappet roller Working in itsface groove to apply oscillatory movement to a main lever 230, shown inFig. 14, andthence by link 231 to an arm 232 keyed to shaft 223. The endof shaft 223, which is extended into the weaving bay (it is shown brokenoff in Fig. 14)

. carry the reeds 238-which form a grating through which the warpspass-one reed passing between each chain of warp threads so that whenthe lay is bumped immediately after the warps cross, the weft threadsare hammered home to close up the weave and fabric as produced in Thereis suflicient clearance between the reeds to allow of the crossing ofthe warp threads.

of push The lever 233 functions also to lift and drop the floating frame239, through a pair links 240 pivotally connected at their ends to lever233 and to frame end members 239. The floating frame is fulcrumed on thefore side of the loom frame on two pivots 241 so that its motionprocured by the movement of links 240 is angular about the pivots 241.This frame carries the top knife which severs the tufts after same havebeen drawn across the shed, the wool selector 311, the pile gage cheeks,the folders, and the pile grlppers. Its function is to lower the partsnecessary to offer clearance for thei-eed and eliminate risk of the reedtouching the gage cheeks or other parts which would be liable to causeit mechanical injury; and after laying, to raise said parts above thetops of the pile gage cheeks.

Floating frame 239 is thusmoved downward with the lay. As shown in Fig.17, the lay frame is guided vertically by guide rails 242 forming partof or attached to vertical members 243244 of the loom frame; the shapeof these members is seen in Fig. 12, but their functioning will be bestunderstood by reference to Fig. 17. As best shown in Figs. 2 and 2,there. is a link connection 245 from the rear end of the floating frame239 to the neck board of the jacquard machine, which will be hereinafterdescribed.

As shown in Figs. 8 and 14, the fourth cam 225, like the third cam 224,is a face groove cam having a roller 246 working in the face groove,said roller being carried on the side of a lever 247 which is connectedat its outer end by link 248 to a long arm 249 forming one bifurcationof the lever which is connected to its distant bifurcation 250 by rib251 which straddles the mechanism carried on shaft 223 between its armmembers 249-250, said intermediate parts being connected with the fifth,sixth, seventh, and eighth cams. The short arm 250 of this bifurcatedlever is connected by link 252 to lever 253 which carries pawl 254acting on a detent wheel 255. said lever 253 being fulcrumed on spindle256 on which detent wheel 255 is mounted. 257 is a check pawl whichoperates to prevent rearward rotation of detent wheel 255. Spindle 256which is, 1

turned by detent wheel 255 carries take off spike roller 167, andthrough intermediate spur gearing 175174 functions to apply motion alsoto the other spike roller 166. At each reciprocation of lever 253, thespike rollers are therefore caused to turn through a definite angle andso to draw off the two split carpets bodily, bringing down the weave inprogressthrough the cheek plates thus applying progressive motion to theThe outer arm of said lever is hung up by spring 270 to a fixed point onthe frame, and said lever is keyed to across spindle 271 extendingacross the weaving bay. The distant end of this spindle, asbest shown inFig. 19, is fitted with an arm 272 which is connected by a correspondingknuckle pin 273 to a pair of toggle arms 274-27 5 corresponding with thetoggle gear 266, to equalize the movement appliedto the folders andobviate springing which would be liable to occur if they were moved by aconnection at one end only. As the toggle mechanism and the folders arecarried on the floating frame, it is necessary to provide for lostmotion between the stud 264 and the knuckle pin 265. This lost motion isprovided by forming a slot in the top of stud 264 for knuckle pir 265 toworkin. Spring 270 functions to bend the toggle and consequently toclose the folders. The closing movement of the folders occurs only whenstud 264 is raised so as to act against pin 265 and spread the togglejoint. The function of the folders is to close in the ends of the piletuft overface wefts 125126. In 25, reed 238 is shown brought down on theface weft over the pile tuft 276, while the floating frame is lowered toprovide clearance for that purpose. As the lay rises the floating framemoves upwardly about one-seventhof an inch, that is sufficiently tobring the lips 277 of folders 27 8 above the level of the front weftthreads 125-126. Then the folders closing in, as will be seen oncomparing Figs. 26 and 27, the ends of the pile tuft 27 6 which wereforced intoan erect position when the floating frame moved upwardly, areinturned so as to bring the edges over to abut, as seen in Fig. 27. Asthe folders come in to close down the ends of the tufts, the warps arecrossed. This is also seen on comparing Figs. 26 and 27. It will benoted that underlying the tuft, a back weft'and a face weft have beenset, that a face weft is inserted in the fold of the tuft and bound inthe crossing of the warps, and that a back and a face weft are insertedin the sheds formed in this crossing of the warps, so that when said newweft threads are closed down the weave is ready to receive another piletuft, as shownin Fig. 23. In order to allow the folders to fold over theends of the tuft, the carpet must be brought down between the gagecheeks a distance equal to the thickness of a tuft quite .irrespectivelyof the floating movement of the frame, because there is no relativevertical movement between the folders and the cheek plates. This advancemovement of the carpet, as before described, is effected by pawl 254 anddetent wheel 255 which is proportioned to turn the spike rollerssufficiently to advance the carpet a distance eiiual to the thickness ofone pile tuft at each reciprocation of lever 253.

Take up rollers 172-173 are turned to roll up the two sections of fabricas formed. Rotational motion is applied to these rollers by pawl anddetent gear, wh1ch is identical on each of them. As shown in Fig. 2, 332is a fine toothed detent wheel fixed to the axle of roller 172; 333 is agravity drop pawl adapted to engage detent wheel 332; 334 is the drivearm of a bell crank lever fulcrumed at 335, and 336 is the power arm ofsaid lever. Arm 336 is connected through a helical spring 337 with link338 pivotally fixed to lever 233 which operates the lay and the floatingframe. In each movement of lever 233 the bell crank lever 334336 isrocked, causing pawl 333 to pick up the teeth of the detent 332 inorder. Rotational movement is applied by pull of the spring 337; thedownward movement of linkage motion 338 operates to engage the pawl.while the pull motion occurs in upward movement of link 338. 339 is thebarrel portion of the roller on which the fabric is wound.

The mechanism for automatically bringing the loom to a stop when any oneof the weft threads breaks is shown particularly 1n Figs. 15 and 16. Asbest shown in Flg. 12, a link 340 from the lever 233, which operates thelay and the floating frame, is connected through linkage to a bell crank341, a link 342, and a horizontal bell crank 343, to a detent rack 344working in a slide guide 391. In a slider 345, four hook pawls 346, 347,348, and 349 are mounted with thelr hooked ends engageable with theteeth of the rack 344. These pawls each carry a light sustaining finger350. These light fingers respectively bear up against the four weftthreads 122 and 125 which pass between them and the fixed studs 351 tothe needles. Fingers 350 may slip past studs 351 as shown in Fi 16 whenthe intervening thread 122 is a ent. When any one of them slips past itsstud (as shown in dotted lines) the corresponding pawl drops and engagesthe rack.

The rack is thus engaged with and operates to move slide 345 and leverarm 352 which is fixed on the top end of vertical spindle 353, andthrough it, as shown in Figs. 1, 14 and 15, to move lever arm 3'54 andthence by means of rod 355 and bell crank 356 to operate control lever357, forcing it into the gate and allowing it to be pulled over to theoff position by tension spring 359. While the belt striker 120 islocated in relation to the fast pulley 119 and the loom is in operation,control lever 357 is held in the jaw of gate 358 as shown in the dottedposition in Fig. 1. hen the throw-ofl gear operates, it is pushed intothe gate, as already described, by bell crank 356, and then pulled tothe off position by spring 359, thus shifting the striking gear to theloose pulley. Control lever 357 is connected by bar 360 with throw arm361 which controls belt striker 120. The starting and stopping of theloom manually is effected by manipulating lever 357. Provision is madefor breakin the motion of the loom when the belt stri er is moved toloose pulley position, by means of a friction band. This band 362, asshown in Figs. 1 and 12, is

flexible and is fixed at one end 363 to the brake when the striker ismoved to'the fast pulley position. Very rapid stopping of the loom istherefore effected through the delicate control provided by the lightfingers 350 while they are sustained by the weft threads 122. Thesethread cease to hold out fingers 350 at the time the normal tension ofthe threads slackens.

The fifth cam 226 applies reciprocating motion through a bifurcatedlever and link mechanism similar to that shown in Fig. 9, to link 279,shown best in Fig. 11, which is connected to an arm 280 on spindle 281,the distant end of which carries another arm 282 connected by link 283to lever arm 284 on spindle 285, said spindle carrying the slottedoperating lever 286 which applies reciprocating motion to the pilegripper device.

As best shown in Figs. 17, 19 and 22, the

pile gripper consists of a base plate 288, the forward part of which isshtted to provide clearance for the warp chains, so that one finger willpass between each chain (see Fig. 17). Pincer jaws 287 of the grippersare similarly slitted and are normally hel d closed by spring 293. Baseplate 288 is formed with two lateral extensions 289 in each of which arectangular guide race 292 is formed. In each of these guide races runsa slide block 291. Each of said blocks carries a bushed pin 290 which isembraced by the walls of a slot 291 in lever 286. The upper ends oflevers 286 are armed with offset pins 295 roller bushed. These rollersco-act with the top side of the tappets 296 which form the back ends ofthe gripper pincers 287. Slide block 291 is shorter than the guide slot292 in which it works, so that there i a certain measure of lost motionfor a purpose hereinafter to be described. The function of the grippersis to cross between the warp chains, take hold of the ends of the tuftwool presented by the wool selectors, and bring the wool thread acrossthe gage cheeks in the manner shown successively in Figs. 22 to 2-1. Inthe .advancing movement toward the tuft wool selector, bushed pins 295bear down on tappets 296 in the manner shown in Fig. 22 and open thepincer jaws a sufiicient distance to insure admission thereinto of theends of the pile tufts as seen at 276 Fig. 22. When the rearward motionof lever 286 commences, the grippers are not immediately withdrawn. butbushed pins 295 leave the tappets 296 and allow springs 293 to act toclose the grippers on wool tufts 276 as shown in dotted lines Fig. 22.As the rearward motion of lever 286 progresses, slide block 291 attainsthe end of the guide slot 292 and then operates to move the grippersoutward across the pile gage cheeks the required distance to draw outthe required tuft length. The grippers are caused to open at this pointby tappets 296 coming against triker rollers 330 carried on brackets 331fixed to the frame, said rollers being positioned to meet the tappetsand depress them. Thereafter the grippers continue to move outward toprovide a clear path for the movement of the lay, leaving the pile tuftsresting between the dents of the warp in the shed.

Oscillating top knife 300 is provided for cutting off the pile tuftswhen they are drawn from the selectors by the grippers and laid acrossthe pile gage cheeks over the lips of the folders, which are formed ascombs to insert between the warp chains. Knife blade 300, as best shownin Figs. 2 and 19, is mounted on an oscillating arm frame 301 which ispivotally supported at 302 .on arms 303 of a pair of bell crank levers,the power arms 301 of which are connected by links 305 to arms 306 on across shaft 261. The angular poisition of knife frame 301 on carrierarms 303 is set by means of spring cushioned tail rods 308 which runthrough holes in lugs 309 on arms 30a of said levers. The purpose of thespring cushioning is to enable the knife face to coact as a scissorblade with a counterpart knife blade 310, best shown in Figs. 22 and 21, which is a fixture behind the rearward folder 278, there beingsufficient clearance for the folder movement between this fixed blade310 and the rearward side of the rear pile gage cheek 161. When the piletuft has been drawn across the weaving slot between the pile gage cheeks(see Fig. 24:) and held there by the gripper jaws, knife 300 is causedto descend and cut off the tufts by scissor action. It is important tonote that when this knife is idle it is retired clear behind the path ofthe lay 236 so that the lay may move without interference from theknife, and that when the knife is brought to the cutting position shownin Fig. 24, lay 236 is in the raised position shown in Fig. 19, so thatthe lay and the reed do not interfere with the knife action. It will benoted that the pile tufts are cut off at some distance in advance of theface of wool selector 311, so that tuft ends are left projecting fromthe selector ready to be picked up on the next movement of the grippersand drawn by the grippers as before between the warp chains.

Arm 306 is turned by shaft 261, and that. shaft which carries the sleeve260 before i mentioned through which motion is transon the eighth cam229. This cam is also set for position so that the movements applied byit are timed, in order that the knife may be caused to descend to cutoff the pile tufts immediately after they have been drawn across thepile gage cheeks to the position shown in Fig. 24.

The function of the 'tuft wool selector, which will be described inconnection with the jacquard machine, is to bring the tufts of requiredcolors to position in relation to the grippers. so that tufts of therequired color will be presented to the respective grippers and by thembe drawn through the warp chains as already described, thereby toproduce the color pattern in the carpet. There is one wool selector foreach dent in the warp chain. These selectors are narrow sector shapedboxes, each subdivided near the curved edge to form mouths for thepassage of a wool tuft 276. They are hung side by side on an arborspindle 315, and are of sufiicient weight, or are-sulficiently weighted,to assure them dropping b gravity, so thatthey will always naturaflyassume their lowest position in which they offer the ground wool tuft276 projecting from the uppermost mouth to the grippers, as shown inFigs. 19 and 22. Arbor spindle 315 is supported in the floating frame,and selectors 311 are raised co nections from the jacquard mechanism tobring one or other of selector mouths 316 into alinement with the ripers, thereby to offer therefrom 'a woof tu of the required colordetermined by the Jacquard action. In each mouth316 a biting sprlng 317of light wire is fitted to bear against the wool yarn 276 therein; andimpose a. little tension on it and prevent accidental drawing back ofthe wool.; The wool yarn is carried into the selectors over a curvedrail 318 from separator guides 319 on the rear frame of the loom, eachline of wool coming from a bo'bbin mounted in some convenient locationclose behind the loom. The tuft wool feed thus depends entirely on thegrippers, the selectors holding the ends of the selected threadspassively available to the grippers. As best shown in Figs. 1, 2, 28, 29and 30, the movement of the several selectors by the jacquard machine iseffected for each one of them by a separate line 320; the jacquardmechanismoperates to move the several selectors to bring the selectedwool tufts about half an inch above the level of the lower jaw of thegripper (see Fig. 22) and then immediately to lower the selector so asto lay the projecting end of the selected wool thread on the gripper jawso that it may be readily secured y the pincer jaw of the grippers. Thisoverlift and drop motion is necessary in order to insure that thegripping of the wool tufts will take place; this would not be certainunless the ends were positively laid in the gripper jaws, as they may becurled or kinked by contact with the apron 321, said apron beingprovided to keep. the wool ends from contact with the elements in frontof the selectors (see Fig. 19). Fins 322 on the apron 321 serve asspacers between the wool selectors to hold them in proper register inwhich forms a stopper above a hole in the relation to the gripper jawsand the dents in the warp chains (see Fig. 18'). wool selector iscontrolled by a lift cord 320. As best shown in Fig. 28, all of saidlift cords are brought around the roller 323 on a bar 324. This barconnects the two links 245 which are pivotallv connected at 325 to therear end of the floating frame 239. Cords 320 are each fastened to aring 326 neck-board 327 of the jacquard machine (see Fig. 28). Rod 324is carried at its ends in a slotted bearing hole 328: in lugs 329 Eachwhich carry the neckboard 327 to allow a certain measure of lost motion.This lost motion device 328 is provided because the 11ft of the acquardmachine framev 368 at the. end of the comb board movement must not betransmitted to the link 245 which,

through the rod 324, connects the neck board rying one pair of cords369. The other cord 369 of each pair is connected to another ringcorresponding with ring 326, which, like it,

is located above another hole in the neck board 327, and is'connected bycord 320 to another of the wool selectors. By grouping the jacquard tailcords in pairs and connecting one cord of each pair to a neck ring, thecross length of the jacquard machine is halved. The number of pairs ofjacquard tail cords in each gang of tail cords is one less than thenumber of months in the wool selectors. In the drawing, five pairs oftail cords are shown in a'jacquard arranged for operating with a6-co-lor wool. selector. In these selectors (see 311 Fig. 19) the groundcolor wool is brought through the uppermost mouth as shown at Fig. 22.The wool selectors are moved by the jacquard from their normal groundcolor position shown in Fig. 22 to any other position to present thetuft of the required pattern color to the gripper. When the jacquarddoes not operate through one of the five pairs of cords on anyparticular selector to raise it to a pattern color position, the woolselector rests at the ground color position (Fig. 22) so that a groundcolor tuft is then offered to the gripper without requiring the jacquardto function to move the selector. As the bulk of the tufts usuallyconsists of ground color, the work thrown on the jacquard is thus verysubstantially diminished, and an advantage of considerable importance isalso attained in that it is not necessary to perforate the jacquardcards for the ground color. A minimum amount of perforation is thereforerequired on the cards and the wear on the cards is consequentlydiminished, and mechanical action in the selectors is minimized.

Thus, for instance, theknots or stop ers on the extreme right hand jacquard cor s (Fig. 28) areengageable by comb board 388' immediately after said comb board hascommenced its rising movement. Neck ring 326 is therefore lifted for themaximum throw of the jacquard, thereby tobring 'the connected woolselector to the position in which it will present the tuft of wool pro-.jecting from its lowermost mouth to the gripper. Similarly, in order,the pairs of tail cords carry their stoppers at different positions sothat on the left of Fig. 28 the stoppers are engaged by the comb boardonly when that board has risen to near the top end of its throw, therebyapplying a minimum rise to the connected wool carrier and so causing itto present the No. 1 pattern color to the gripper.

needles to neutral position. In the" right hand movement the card 394 onjacquard cylinder 372 is brought up to the needle points and 0 rates tomove inward those needles whic contact with unperforated portions of thecard, and thereby through the eyes on said needles to move tail cords369 associated with the particular needles that have been so moved alitle out of the normal vertical line. The holes in the comb board (aswill be seen on reference to Fig. 29) are key-hole shaped. When jacquardtail cords 369' are in normal vertical position in register. withthe'wide portion of the comb board holes, the comb board passes stoppers 387without lifting the cords, but conversely when any cord isin'registerwith the slot portion of its comb board hole, its stopper 387is engaged above the slot and the comb board operates to lift the tailcord. Comb 'board 388 is vertically reciprocated on jacquard frame 368by means of arm 396 keyed to, rock spindle 397, which extends across theframe and carries at itsdistant end an operating arm 398 which isconnected by link 399, as shown in Fi .12, to lever arm 400which-carries an 0 set roller pin working in a cam groove on the side ofseventh cam 228. The connection between lever 396 and comb board 388 isthrough a slot and pm connection 401, 402 being foot brackets on thecomb board which carry pins 401. 403 are half guides which hold the combboard 388 in vertical alinement.. They run on frame 368, and at topstroke of. the comb board they contact with adjustable tappets 404 fixedon frame 368, and when they so contact they apply a lifting movement tojacquard frame 368, being a movement of about half-an-inch. Thismovepers 387 or not. Each of the tail cords 369 is amociated with aseparate jacquard needle 389 in the usual way known in jacquardpractice. The jacquard mechanism, however, includes the novel feature ofthe frame lifting motion which offsets the half inch extra lift appliedto the wool selectors for the purpose of setting the ends of thepresented tufts with certainty within the aws of the grippers. Thefeature of wool rot : selectors havingan idle position'in which theground color wool is presented to the grippers without operation of thejacquard, thereby, asalready described, effecting a saving in needleoperation, and cost of preparing cards and wear and tear on cards isalso a feature within the invention.

Depending on the number of heddles used, one arrangement being shown inFigs. 2 and 3, and the other in Figs. 32 and 33, the arrangement of thewarp chains is altered. vA.

section of the weave made according to Figs. 2 and '3 arrangement isshown in Fig. 31, while in Fig. 34 is shown a section of the weave whichis made by the five heddle ar-, rangement as in Figs. 32 and 33. .In thecase of the three heddle arrangement, a stationary warp 53 is setbetween the pairs of back weft threads 122 and face weft threads 125,the back and face warps forming a bonding chain, each loop of whichincludes two double face wefts and one double back weft, the fold of thetuft showing on the back of the fabric'between the pairs of back weftthreads. It will be noted that the back wefts are located midway of thetwo pairs of face wefts, with the fold of the tufts intervening betweenthe pairs of back wefts and exposed on the backof the fabric. In thecase of the five heddle weave, the back wefts are located in pairsimmediately behind pairs of face wefts, while additional pairs of facewefts are located between said face wefts which are backed by the backwefts. A stationary warp 406 sets between the lines of face wefts andback wefts while the warps are alternated forming cross chains, eachwarp in turn coming over a pair of face wefts, then under a pair of backwefts, then behind a pair of face wefts, then up over a pair of backwefts, and so on, so that each pair of face wefts is bound in a chainwhile the back wefts are tied by a separate chain interlocked with theface weft chain, bonding the folds of the tufts between the pairs ofback wefts and the pairs of face wefts, thus secreting the folds of thetufts from view at the back of the carpet and leaving spaces.intervening on the back of the carpet between each pair of bonded backwefts. A corrugated appearance on the back of the carpet is thusobtained in the case of Fig. 34 weave which is effected with the fiveheddles, while inthe case of Fig. 31 weave effected with three heddlesthe clearance which appears between the face and back wefts in Fig. 34is occu ied by the folds of the tufts, givingthe ack of the fabric afuller appearance. In order to permit the operation of the five heddlearrangement and to provide for the difference in length of the facewarps and the backand-face warps respectively, these warps must be drawnofi' separate beams, inasmuch as the length ofback-and-face-weft-bonding warp is considerably of t e faoe-we'ft-boning warp. 407 is the beam which carries the face-weft-bonding warps 408,and 409 is the beam which carries the back-and-face-weft-bondin warps410. The five heddles are respective y numbered 411, 412, 413, 414, and415.- The second (412) and the fifth (415-) heddles are operated bylinkages 88 and 89 correspondingwith the linkages already described withre erence to the heddle arran ement in Fi 2 and 3 the additional h dles,being t e third and fourth in the series, numbered respectively 413 and414, are respectively moved by lost motion connections from secondheddle 412 and fifth heddle 415. This lost motion arrangement consistsof pin and slot plate devices 416 which permit a certain degree ofmovement of the driving heddles one way-or the other before motion isapplied from them, to driven heddles 413 and 414. The lead and cro$ingof the warps to form the warp chains shown in Fi 34 will be seen byfollowing the course of the warps in sequence as shown in Figs. 32 and33.

Beams 55 and 407 are fitted with friction bands identical with the band58 shown in Fig. 2, and the warp threads drawn from them are maintainedin tension by the action of these, friction bands. Beam 409 ispositively turned by worm gear identical with the worm gear 65- 66 shownin Fig.2.

Instead of using a system of wool selectors controlledby a jacquardmachine as described, I may use the known method of presenting the wooltufts in order to form the pattern, which consists in using a chain ofbobbins, 'each bobbin wound with woo-l threads in selected order for thepattern.

In that case the jacquard is entirely dispensed with and the tufts arepresented to be taken by the grippers from the several bobbins on thechain in successive order. This system is appropriate where the loom isrequired to roduce considerable quantities of goods of practicable withit to provide for an unlimited number of bobbins, thus offeringunrestricted opportunity for forming a patreater than the length thesame pattern, and it is tern irrespectively of the length betweenrepeatpoints, or the number of colors required in the pattern.
